I think east German quality control was same than Russian means nothing...
With mark or without mark you can find either excellent and average lenses.

My Meyer Trioplan has got a 1 in a triangle, Aus Jena Sonnar 135 zebra has 1Q, so does my Tessar 80/2.8 for the Pentacon.

So... 1Δ for export and 1Q for home market?

No.

1Q for export. Quality (optical? mechanical? both?) Above over international parameters.


1Δ For export. Quality equal to international parameters.

1V for home market.

In this way I read the article.

According to my Zeiss Compendium book the 1Q (primarqualitat) mark was given to the lenses of the highest quality to be sold on the western market. Items whose quality was a slightly lesser grade was given a 1 or 2 within a triangle.
The quality control was administered by the Office of Material and Product Testing of the German Democratic Republic. The testing started in the mid - 1950's and continued for more than two decades.

I added a bit more info to my original post. the testing started in the mid 1950's and ran for more than two decades.
According to the authors the Praktica MTL-3 from 1978 still bears the 1Q mark but the mark was phased out shortly thereafter but the same quality testing continued until the reunification of the two Germanies in 1989.

My Tessar is serial number 4.4million, which would put its manufacture date around the summer of '56. So the system was definitely operating then.

Anyone got an earlier datable lens with the marking?

My Biotar is a 359 serial #, my Tessar 50mm 2.8 is a 532 serial #, and my Triotar is 518 serial #.

All marked 1Q.

Serial number and dates? Anyone have a list?

Errr, yes, it is up one level in this forum, and there is a handy graph. The 383xxxx lens appears to be early 54

The mark is also present on Meyer-Optik lens. Can the same interpretation to the 1Q logo be applied to them too?



Embarassed After posting the above pic and question, I noticed that the link Rino pasted show Meyer-Optik has the same logo too. Embarassed Embarassed

Hi, Bawang.

It seems to me that your lens is something yellow; isn't it?

The S in the quality mark means, that the quality is Sufficient
